a lstud axle '16 monntedin their AFigs. 1 and in the form of rollers,which project from ythe inner surface ofhthe disk 17 so as to registerwithgandlhengage thewrecesses in 'the ends of the cross heads, ashereinafter described. The studs 18, 18 and 18') are equally distantfrom the center of the` disk 1-7 and equally distant4 from each other`rl`he parts move in the direction indicated b v the arrows in Thediameter of the disk 17 and the location of the studs thereon is suchthat the circle in which said studs travel will' intersect the circle inwhich the axis ol' said folding blade travels above the folding rollersat the point of engagement of said stnds with the cross head and at thepoint at which said studs disengage the said cross head.

1Q indicates a circular guide supported will hold the Cross heads andtherefore the foiding blade in normal inoperative position Whiletraveling around with the carrier nntll the folding movement is'made,the guide being ont away at its bottom above the folding l en rollers 9to permit the folding operation.

In practice the rotary carrier 5 is prefer ably used as one member of atransverse cntting mechanism, and is therefore provided with usual slots2-1 which cooperate with a knife 22 on cutting cylinder' 225 to severthe pa er transversely,

he operation of the above-described de.- vices is as follows :--'l`heparts rotating in the direction indicated by arrows in Figs. 1 and 2,the cross heads 1() travel around in the -guide 19 holdingr the foldingblades in normal position until one of the cross heads reaches the openspace at the bottom of the guide.. At this mo1nent,.with the gear 15 andtherefore the disk 17 .rotating in the same direction as the rotarycarrier, the cross head overtakes the roller 18, as shown in Fig. 1, andcauses the said roller to engage the re cess in the lead end ofthe crosshead. As the parts continue their rotation, by the interengagement ofthe stud 18 and the recess inthe cross head, the cross head will bemoved into the position shown in solid lines in Fig. 2,-that is to say,with the blade in the vertical plane between the, rollers Sis-'4),- thustncking the paper between the folding rollers Q-Q and rausing it to befolded. As the'rotation continues, thee-ross head, by theinterengagenient of the stud 18 in the. recess in the said cross head,will be moved ont of folding position. and. back into normal position,vshown'in dotted lines in Fig. 2, at which point the cross head and thestud will se arate from one another and the stud be re eased 'from thesaid recess,.the cross head being thus delivered in normal position tothe guide 1S) to be carried around thereon. As the rotation continues,the, lead end of the opposite cross head will be engaged in the samemanner and operated b v the stud 1S", skipping' the stud la, lipon thecompletion ol' the next semi revolution of the carrier, the lead end ofthe cross head 'first engaged, which will be the opposite end from thatfirst engaged, will be engaged by the roller 1S, the roller 1S beingpassed over` and the folding operation again completed.

3y driving the gear and therefore the disk 17 at a. rate which compareswith the rate of rotation of the rotar)Y carrier as four to three, and bv providingr the disk 1T with three studs equally` distant from eachother, that is to say, one hundred and twenty degrees apart, l am.enabled io operate the folding blade -in a proper curve both on movinginto and on. moving ont of folding position, so that the papel' may beproperly folded, and, as has been said above, by so placing the ro tarydisk 1T that its axis ol' rotation comes between the axis of the rotarycarrier and the circle on which the axis of the folding blade travels,l. am enabled to operate the slotted cross head both into and ont offolding position by a single rotating disk.

lt wifl, of course, be understood that the rotary carrier has inpractice a web of pa. ier delivered to it from a printing press or otier mechanism, and that theI web of paper is car ried around the.carrier by means of suitable pins, as 24, or other mechanism of anywellknown and approved construction, but for purposes of elearness ofillustration I have not shown the web of paper in the drawings, as themanner in which my improved folding mechanism acts upon it will beclearly understood by those skilled in the art.

What I. elaim as my invention and desire to secure by liettcrs latent isz- 1. The combination with a rotary carrier, a folding blade carriedthereby, a cross head connected with said folding blade and providedwith a recess at each ond, and foldeoinpleting mechanism, of a rotarymember placed with its axis of rotation between the, axis of rotation ofsaid rotary carrier and the, line of travel of said folding blade androtating in the same direction as said rotary carrier, and an eingaginirstud on said rotary member adapted, while .traveling in tho samedirection therewith, to engage said recessed cross head while. saidcross head is in normal position, and, by its said engagement therewithand while traveling in the same. direction, to operate said cross headand move said folding blade into folding position and' ont of foldingposition. into normal position.
